A 16 channels heterodyne radiometer is being developed on HT-7 superconducting tokamak. The received frequencies of the radiometer are from 98 to 126 GHz. The local oscillators are 95 GHz for the low field side and 108.5 GHz for the high field side. After using the SSB mixers, the frequency is down converted to 2-18 GHz and detected by the detectors. The spatial resolution of the system is about 2cm and the temporary resolution is 1 ¿s approximately. The electron temperature profile of the core plasma was measured by the ECE radiometer.
